Frank is such a great visual storyteller, that if you study his artwork you see that his Sin City books are already the best movies never seen on the big screen.
What I love about new technology is that it really pushes the art. It really pushes it in a way that you can't imagine until you come up with the idea. It's idea-based. You can do anything.
The challenge is what was making it exciting. You don't want to do anything that's too easy or that you know that you can pull off, otherwise it's really not worth doing.
